Extracorporeal shock wave lithotripsy as first line treatment alternative for urinary tract stones in children: A large scale retrospective analysis

Purpose: Management of urinary tract stones in children represents a challenging problem. In this study we retrospectively analyzed our experience with extracorporeal shock wave lithotripsy (SWL) in children

Polymorphism of endothelial nitric oxide synthase gene in patients with erectile dysfunction

Introduction. Endothelial-derived nitric oxide (NO), which is produced by endothelial nitric oxide synthase (eNOS) in response to increased blood flow, maintains the tumescence phase of erection. The eNOS gene is located on the seventh somatic chromosome and the polymorphism of this gene has been reported to cause changes in the structure of enzyme system, resulting in disturbance of its activity

Fournier's Gangrene Severity Index on the outcomes

Fournier's gangrene (FG) is a rare, rapidly progressive, fulminant form of necrotizing fasciitis of the genital, perianal and perineal regions. Several factors have been reported to contribute to the clinical outcomes. The primary aims of this study were to examine the clinical features of patients with FG and evaluate the predictivity of the Fournier's Gangrene Severity Index (FGSI) score on the outcomes. We carried out a collective retrospective chart review of patients diagnosed and treated for FG in three reference centers between January 1995 and July 2007. Seventy-two patients with FG with were included to the study. Data were collected on medical history, symptoms, physical examination findings, admission and final laboratory tests, timing and extent of surgical debridement and antibiotic therapy. Perianal and perirectal abscess, scrotal abscess and urethral stenosis were the leading etiological factors. Diabetes mellitus was the predominant risk factor. Etiological factors and risk factors did not significantly contribute to survival or mortality, and duration of the symptoms was significantly longer in the non-survivor's group (P < 0.05). The FGSI scores were higher in the non-survivor's group. Regression analysis showed a FGSIS score of 10.5 as the cut-off to the outcome. Based on these results, we conclude that a patient's metabolic status and the extent of disease at presentation are the most important factors determining the prognosis of FG. The FGSI score may be considered as an objective and simple tool to predict the outcome in the patient with FG and should be used in further studies of FG patient series for comparison purposes

Are patients with lichen planus really prone to urolithiasis? Lichen planus and urolithiasis

WOS: 000380066200025PubMed: 27286123Purpose: to investigate whether patients with lichen planus (LP) are really prone to urolithiasis or not. Patients and Methods: We performed a prospective analysis of 40 patients diagnosed with lichen planus (LP) (group I), and 40 volunteers did not have LP before (group II). Participants were all checked for urolithiasis by radiological investigations. Blood samples were analyzed for biochemistry parameters including calcium and uric acid. 24-h urine samples were analyzed to investigate oxalate, citrate calcium, uric acid, magnesium, sodium and creatinine. Results: Men/women ratio and mean age were similar between group I and II (p> 0.05). A presence or history of urolithiasis was detected in 8 (20%) and 2 (% 5) patients in group I and II, respectively (p< 0.05). Hypocitraturia was the most common anomaly with 35% (n: 14) in group I. The rate of hypocitraturia in group II was 12.5% (n: 5) and the difference was statistically significantly different (p= 0.036). In group I, hyperuricosuria and hyperoxaluria followed with rates of 27.5% (n: 11) and 25% (n: 10), respectively. The rate of hyperuricosuria and hyperoxaluria were both 5% (n: 2) in group II and the differences were significant (p< 0.05). Hyperuricemia was another important finding in the patients with LP. It was detected in 13 (32.5%) patients in group I and in 1 (2.5%) participant in group II (p= 0.001). Conclusion: According to our results, metabolic disorders of urolithiasis were highly detected in the patients with LP. However, similar to the etiology of LP, the exact reasons for these metabolic abnormalities in LP remain a mystery
